Abstract
The invention discloses a kind of cement production process, and cement is made as follows：Batch mixing：Lime stone, clay, iron powder and muscovite are sufficiently mixed；It is levigate：By the raw material mixed fully it is levigate after obtain raw material；Calcining：The raw material being mixed to get are calcined at a high temperature of 1400 DEG C 1600 DEG C, carry out row's alkali process simultaneously in calcination process, control alkali content is less than 0.5 weight accounting, the gypsum in product, clinker and mixing material are separated, obtain clinker；Mixed modifier：The clinker of cement modifier and separation is stirred mixing, obtains cement products.Advantages of the present invention：Cement consolidation stress after being handled by doping vario-property is remarkably reinforced, and hole is filled by the addition of flyash and nano material, the heat of hydration of cement can be effectively reduced, and modified cement drying shrinkage is small, later strength is high, bleeding rate is low.
Description
Technical field
The present invention relates to building material, more particularly to a kind of cement production process.
Background technology
In recent years, the fast development of China's infrastructure, the dosage of cement continues to rise, and cement industry is as a height
The serious industry of energy consumption, high resource consumption, environmental pollution.In the background of current " sustainable development " and " energy-saving and emission-reduction " policy
Under, the development of cement industry is faced with huge challenge and impact.Cement production process power consumption of the prior art is big, production capacity
It is low, in addition, also have the cement products being doped using modifying agent in the prior art, but it is generally the structure for cement
Influence is smaller, causes to add processing cost, and does not cause too much influence to the substantive mechanical property of cement, production
The shortcomings that heat of hydration is high, consolidation stress decline is fast still be present in cement.
The content of the invention
The defects of for prior art and deficiency, it is an object of the invention to provide a kind of drying shrinkage is small, later strength is high,
The low cement production process of bleeding rate.
To achieve the above object, the technical solution adopted by the present invention is：A kind of cement production process, its innovative point be,
Cement is made as follows：
Batch mixing：Lime stone, clay, iron powder and muscovite are sufficiently mixed；
It is levigate：By the raw material mixed fully it is levigate after obtain raw material；
Calcining：The raw material being mixed to get are calcined at a high temperature of 1400 DEG C -1600 DEG C, in calcination process simultaneously
Row's alkali process is carried out, control alkali content is less than 0.5 weight accounting, the gypsum in product, clinker and mixing material is separated,
Obtain clinker；
It is mixed and modified：The clinker of cement modifier and separation is stirred mixing, obtains cement products.
Further, the cement modifier compounds admixture by calgon, micro- silicon and carbon fiber forms.
Further, the content of the calgon is account for clinker weight 10%, micro- silicon compounding admixture
Content is account for clinker weight 7.5%, and the content of the carbon fiber is account for clinker 0.5%.
Further, the flyash for accounting for lime stone weight 30% can also be added in the mixing process.
Further, the content of the muscovite is account for lime stone weight 10%.
The present invention has the beneficial effect that：
Cement consolidation stress after being handled by doping vario-property is remarkably reinforced, and passes through flyash and nanometer material
The addition of material is filled hole, can effectively reduce the heat of hydration of cement, and modified cement drying shrinkage is small, the later stage
Intensity is high, bleeding rate is low.
Brief description of the drawings
Fig. 1 is the process chart of the present invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with embodiment pair
The present invention is further elaborated.It should be appreciated that embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1 process chart, present embodiment discloses a kind of cement production process, and its innovative point exists
In, as follows be made cement：
Batch mixing：Lime stone, clay, iron powder and muscovite are sufficiently mixed；In the another embodiment of the present invention
In, the flyash for accounting for lime stone weight 30% can also be added in mixing process.The content of the muscovite is to account for lime stone
The 10% of weight.Preferably, Nano zinc dioxide impact-resistant and nano silicon can also be added in compound as pore filling agent,
It is set to calcine to be filled the hole of formation so as to strengthen the consolidation stress of finished ground cement in powder.And use
Flyash can effectively reduce the heat of hydration of cement after being mixed.
It is levigate：By the raw material mixed fully it is levigate after obtain raw material；
Calcining：The raw material being mixed to get are calcined at a high temperature of 1400 DEG C -1600 DEG C, in calcination process simultaneously
Row's alkali process is carried out, control alkali content is less than 0.5 weight accounting, the gypsum in product, clinker and mixing material is separated,
Obtain clinker；
It is mixed and modified：The clinker of cement modifier and separation is stirred mixing, obtains cement products.
Feasible, the cement modifier compounds admixture by calgon, micro- silicon and carbon fiber forms.Wherein, institute
The content for stating calgon is account for clinker weight 10%, and the content of micro- silicon compounding admixture is to account for clinker weight
7.5%, the content of the carbon fiber is account for clinker 0.5%.Modified cement drying shrinkage is small, later strength is high, bleeding rate
It is low, and consolidation stress is not in still that stress reduces after consolidating 30 days.
It is described above, it is merely illustrative of the technical solution of the present invention and unrestricted, those of ordinary skill in the art are to this hair
The other modifications or equivalent substitution that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
It all should cover among scope of the presently claimed invention.
